considered as contamination.- With back to hazard, scan slowly with contamination meter 2-5 cm from surface of personal protective equipment (PPE) with priority to boots and gloves.

Final Decontamination:

- Portal Monitor: Proceed into the Portal Monitor, pause for 5-10 seconds, then rotate 90 degrees and pause again for 5-10 seconds to ensure all four sides of the person are monitored. If alarm sounds, remove PPE and proceed to Secondary Bench. If PPE was already removed prior to using the Portal Monitor or no Portal Monitor is available, move to the Primary Bench.

Remember: most Portal Monitors only detect gamma radiation, therefore monitoring at the Primary Bench is still required.

- Primary Bench: Full-body monitoring, starting with hands (both sides), then head, arms (extended out to the side), torso, legs and bottom of the feet (the entire process should take approximately five minutes). Remove contaminated PPE after any measurement exceeding twice background. Once PPE is removed, proceed to Secondary Bench. Clean persons may exit at this point.

- Secondary Bench: Repetition of full-body monitoring (with PPE off) and all decontamination cleaning are performed at this location. The least aggressive method should be used to clean the skin. Avoid abrading the skin (wet wipes are effective and easy to dispose of). Any removed clothing must be bagged and tagged.

- Once clean, person and/or object may exit.
